Last Updated June 14, 2022 | Hamilton Schutt

A fresh cabin air filter will keep pollen, smoke, mold, and dust from polluting your S550’s interior. On average, you should replace the cabin filter every 10,000-20,000 miles to improve airflow, eliminate bad odors, and keep your windows from fogging up. This guide will walk you through how to replace a bad cabin air filter and give you some filter replacement options for your 2015-2022 Ford Mustang.

Filter Replacement Process

Replacing your S550’s air filter only takes 10-20 minutes and can save you upwards of $40 over the dealership’s rates. This process is the same for all 2015-2022 Mustangs.

  • T20 Torx Driver
  • Flashlight (Recommended)

Step 1: Open Glove Box

Open your empty glove box to the extended position and push the track on the right side in, up, and out to release the glovebox from the dash.
